Determine the range, variance, and standard deviation for the sample data.

Solutions

Expert Solution

solution:-
given values are 5176,6005,5052,5310,4188,4132,5736,5381,4983,4423,5002,4573,4209,5611,4568
range :-
The lowest value is 4132
The highest value is 6005
The range = 6005 - 4132 = 1873

variance = 350882.4

explanation

standard deviation :-

sqrt(variance) = sqrt(350882.4)

= 592.35

A University Library has many items available for its students; some can be checked out and others cannot. Among those that can be checked out are journal (i.e., a literary journal) and digital video disk (i.e., a DVD). These two types have many attributes in common such as title, publisher, and dewey decimal classification. Design a class to represent the library item that would capture the common features among journals and DVDs. Then, design journal and digital video classes that...
